Reil [10]

You just need to multiply 9 1/2 by 11 3/4. simplify these into decimals: 9.5 and 11.75

Then do 9.5*11.75=111.625

The length of a rectangle is 1 less than twice the width. Write the equation that could represent the area of the rectangle in t

Ipatiy [6.2K]

Answer:

(W2-1)xW

Step-by-step explanation:

The beginning of the equation represents the length as the question states it is one less than twice the width. Because you need to multiply width and length to get area, you place the length equation and parentheses and multiply the answer to the equation by the width :) Hope this helps!

The length of one base of a trapezoid is 19 less than five times the length of the other base. If the trapezoid has a height of

ycow [4]

The length of the longer base is 41 ft.

<u><em>Explanation</em></u>

Lets assume, length of one base is $x$ ft.

As, another base is 19 less than five times the length of this base, so the length of another base $= (5x- 19) ft.$

The trapezoid has a height of 18 ft and area of 477 ft²

Formula for Area of trapezoid, $A=\frac{1}{2} (a+b)*h$ , where $a, b$ = Two bases of trapezoid and $h$ = height of the trapezoid.

Given in the question: $A= 477$ and $h= 18$

We have also two bases as: $a= x$ and $b= 5x-19$

So, according to the above formula...

$A= \frac{1}{2}(a+b)h\\\\ 477=\frac{1}{2}(x+5x-19)*18\\\\ 477=9(6x-19)\\\\477= 54x-171\\\\477+171=54x\\\\648=54x\\\\x=\frac{648}{54} = 12$

So, length of one base is $12 ft$ and another base $=(5*12-19)ft =(60-19)ft = 41 ft$

That means, the length of the longer base is 41 ft.

The distance traveled (d) varies directly as the time (t) of

Helen [10]

Answer:

2.70 hours to travel 180 mi.

Step-by-step explanation:

The distance traveled (d) varies directly as the time (t) of travel, by the following formula:

$s = \frac{d}{t}$

In which s is the velocity.

It takes 63 min to travel 70 mi.

So i am going to find the velocity in miles per minute

$s = \frac{70}{63} = 1.11$

how many hours would it take to travel 180 mi?

I am first going to find the time in minutes, then divide by 60 to pass to hours.

$s = \frac{d}{t}$

$st = d$

$t = \frac{d}{s}$

$t = \frac{180}{1.11}$

$t = 162.16$

It takes 162.16 minutes = 162.16/60 = 2.70 hours to travel 180 mi.

5 inches is what fraction of a foot?

3241004551 [841]

Answer:

5 inches out of a foot would be a fraction 5/12.

Step-by-step explanation:

Because a foot is 12 inches, your bottom number of the fraction (the one on the right) would be 12 inches and the 5 inches would go on the top of the fraction (or, on the left; depends on how you write it).
